No single best speaker here - they are built to different priorities, and the right one depends on your room, your sources and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | Buchardt A700 digs deeper - 17Hz against 31Hz. |
| Built-in power | A | KEF LS60 Wireless has the bigger amplifier (1400W vs 600W RMS). |
| Connections | A | KEF LS60 Wireless adds Bluetooth, streaming, HDMI and digital inputs. |
| Size | depends | Buchardt A700 is easier to place; KEF LS60 Wireless is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | A | KEF LS60 Wireless: a sub output. KEF LS60 Wireless sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | A | KEF LS60 Wireless is cheaper - $4,999 against $6,600, about 24% less. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KEF LS60 Wireless is the easier recommendation: it leads on most of the measured areas and costs less. Take Buchardt A700 if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 31Hz anyway, which makes the cheaper KEF LS60 Wireless much easier to justify. In a large or open-plan room, KEF LS60 Wireless has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Buchardt A700 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
